What is (med) & also what is accelerator? I painted cars in the lacquer days & used it on humid days to speed dry the clear.
(Med) is the viscosity or thickness of the super glue that is best used to fill in dents.
There is Thin (almost like water and will penetrate wood deeply),
Medium (the normal stuff),
Thick (fills gaps),
and Gel (commonly used for tips).
Accelerator is a chemical that will set the superglue upon contact.
It forces the glue to harden.
Sometimes a puddle of superglue will take hours to set unless you hit it with Accelerator.
Problem here is that sometimes the accelerator will fog the glue and it wont be clear.
